* Recommit rL245802: Cleanup fancy pointer rebinding in list using ↵Eric Fiselier2015-08-231-0/+27
| | | | | | | | | | | | __rebind_pointer. Currently we need an #ifdef branch every time we use pointer traits to rebind a pointer because it is done differently in C++11 and C++03. This patch introduces the __rebind_pointer utility to clean this up. Also add a test that list and it's iterators can be instantiated with incomplete element types. llvm-svn: 245806
* Refactor shared_timed_mutex tests.Eric Fiselier2015-08-2221-146/+119
| | | | | | | First I removed all of the uses of _LIBCPP_STD_VER and added LIT UNSUPPORTED tags to prevent the tests from being run in older standard dialects. Second I increased the time tolerances used in some tests when testing with Thread Sanitizer because thread sanitizer make these tests take longer. llvm-svn: 245793

* Remove test_atomic.h headerEric Fiselier2015-08-193-10/+10
| | | | | | | Because <atomic> can now be used in C++03 there is no need for the test_atomic.h header. This commit removes the header and converts all usages to use <atomic> instead. llvm-svn: 245468
* [libcxx] Allow use of <atomic> in C++03. Try 3.Eric Fiselier2015-08-1930-675/+268
| | | | | | | | | | | | | | | | | | | | | | | Summary: After putting this question up on cfe-dev I have decided that it would be best to allow the use of `<atomic>` in C++03. Although static initialization is a concern the syntax required to get it is C++11 only. Meaning that C++11 constant static initialization cannot silently break in C++03, it will always cause a syntax error. Furthermore `ATOMIC_VAR_INIT` and `ATOMIC_FLAG_INIT` remain defined in C++03 even though they cannot be used because C++03 usages will cause better error messages. The main change in this patch is to replace `__has_feature(cxx_atomic)`, which only returns true when C++ >= 11, to `__has_extension(c_atomic)` which returns true whenever clang supports the required atomic builtins. This patch adds the following macros: * `_LIBCPP_HAS_C_ATOMIC_IMP` - Defined on clang versions which provide the C `_Atomic` keyword. * `_LIBCPP_HAS_GCC_ATOMIC_IMP` - Defined on GCC > 4.7. We must use the fallback atomic implementation. * `_LIBCPP_HAS_NO_ATOMIC_HEADER` - Defined when it is not safe to include `<atomic>`. `_LIBCPP_HAS_C_ATOMIC_IMP` and `_LIBCPP_HAS_GCC_ATOMIC_IMP` are mutually exclusive, only one should be defined. If neither is defined then `<atomic>` is not implemented and including `<atomic>` will issue an error.

* Mark std::packaged_task tests as unsupported in C++03.Eric Fiselier2015-08-1918-61/+45
| | | | | | | std::packaged_task requires variadic templates and is #ifdef out in C++03. This patch silences the tests in C++03. This patch also rewrites the .fail.cpp tests so that they use clang verify. llvm-svn: 245413
* [libcxx] Add Atomic test helper and fix TSAN failures.Eric Fiselier2015-08-187-136/+148
| | | | | | | | | | | | | | | | | | | Summary: This patch attempts to fix the last 3 TSAN failures on the libc++ bot (http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-tsan/builds/143). This patch also adds a `Atomic` test type that can be used where `<atomic>` cannot. `wait.exception.pass.cpp` and `wait_for.exception.pass.cpp` were failing because the test replaced `std::terminate` with `std::exit`. `std::exit` would asynchronously run the TLS and static destructors and this would cause a race condition. See PR22606 and D8802 for more details. This is fixed by using `_Exit` to prevent cleanup. `notify_all_at_thread_exit.pass.cpp` exercises the same race condition but for different reasons. I fixed this test by manually joining the thread before beginning program termination.

* [libcxx] Fix PR23589: std::function doesn't recognize null pointer to ↵Eric Fiselier2015-08-181-0/+247
| | | | | | | | | | | | | | | | | | | | varargs function. Summary: This patch fixes __not_null's detection of nullptr by breaking it down into 4 cases. 1. `__not_null(Tp const&)`: Default case. Tp is not null. 2. `__not_null(Tp* __ptr);` Case for pointers to functions. 3. `__not_null(_Ret _Class::* __ptr);` Case for pointers to members. 4. `__not_null(function<Tp> const&);`: Cases for other std::functions.

* Fix failing unique_ptr tests.Eric Fiselier2015-07-312-38/+7
| | | | | | | | When I was refactoring the unique_ptr.single.ctor tests I added a test deleter, 'NCDeleter', to deleter.h. Other tests that include deleter.h redefine the NCDeleter type causing test failures. llvm-svn: 243733
* Start cleanup of unique_ptr tests.Eric Fiselier2015-07-3128-1575/+894
| | | | | | | | | | | | | | | | One of the last sections of tests that still fail in C++03 are the unique_ptr tests. This patch begins cleaning up the tests and fixing C++03 failures. The main changes of this patch: - The "Deleter" type in "deleter.h" tried to be "move-only" in C++03. However the move simulation no longer works (see "__rv"). "Deleter" is now copy constructible in C++03. However copying "Deleter" will "move" the test value instead of copying it. - Reduce the unique.ptr.single.ctor tests files from ~25 to 4. There is no reason the tests were split through so many files. llvm-svn: 243730

* Cleanup <__functional_03>Eric Fiselier2015-07-229-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | <__functional_03> provides the C++03 definitions for std::memfun and std::function. However the interaction between <functional> and <__functional_03> is ugly and duplicates code needlessly. This patch cleans up how the two headers work together. The major changes are: - Provide placeholders, is_bind_expression and is_placeholder in <functional> for both C++03 and C++11. - Provide bad_function_call, function fwd decl, __maybe_derive_from_unary_function and __maybe_derive_from_binary_function in <functional> for both C++03 and C++11. - Move the <__functional_03> include to the bottom of <functional>. This makes it easier to see how <__functional_03> interacts with <functional> - Remove a commented out implementation of bind in C++03. It's never going to get implemented. - Mark almost all std::bind tests as unsupported in C++03. std::is_placeholder works in C++03 and C++11. std::is_bind_expression is provided in C++03 but always returns false. llvm-svn: 242870
